Insert more than one space into character variable

[ Edited ]

Hi all,

I have string value:

 Cohort 33 / 0.1 mg/kg

and have to add 3 more empty spaces between slash and 6, like this one:

 Cohort 39 /   0.2 mg/kg

What is the best solution for the case? Transword and simple concatination are not working.

Re: Insert more than one space into character variable

Straight forward:

data test;
length string \$30;
string = 'Cohort 9 / 7 mg/kg';
string = substr(string,1,indexc(string,'/')+1) !! '   ' !! substr(string,indexc(string,'/')+2);
run;

The name of the function is tranwrd not transword.

string2=tranwrd(string,"/ ","/   "); /*works*/

Re: Insert more than one space into character variable

Remember if you are attempting to do this with the source variable as the target variable, insert in place as it were, the length of the variable better be long enough to accept the additional characters or you may get truncation.

See this slight modification of the solution to demonstrate:

data test;
length string \$19;
string = 'Cohort 9 / 7 mg/kg';
string = substr(string,1,indexc(string,'/')+1) !! '   ' !! substr(string,indexc(string,'/')+2);
run;
